[0036] The embodiments of the present application will be further described below with reference to the accompanying drawings. Those skilled in the art should understand that the embodiments described in the present application are only exemplary embodiments.

[0037] Next, the embodiments of the present application will be described with reference to the accompanying drawings.

[0038] As shown in Figures 1 to 10 The present application provides a tendon and internal support auxiliary fixing device for a servo hydraulic machine, which comprises an upper fixing mechanism 1, a clamp mechanism 2, a clamp base 3 and a lower fixing mechanism 4.

[0039] As shown in Figure 2 The upper end of the upper fixing mechanism 1 is provided with an upper fixing base plate 11 for fixed connection with the upper mechanical arm of the servo hydraulic machine. The lower part of the upper fixing base plate 11 is provided with a fixed seat 13. The fixed seat 13 is provided with a cross beam sliding groove 16 and an upper moving cross beam 12 which is arranged in the cross beam sliding groove 16 and can move up and down in the cross beam sliding groove 16. The upper moving cross beam 12 is arranged in a vertical direction with a gap from the fixed seat 13, that is, there is a certain distance between the upper and lower ends of the upper moving cross beam 12 and the fixed seat, so as to ensure the position of the upper moving cross beam in the cross beam sliding groove. The size of the gap between the upper moving cross beam and the upper and lower ends of the fixed seat can be adjusted according to the needs.

[0040] The upper fixing base plate 11 is provided with a connecting hole 17 for fixed connection with the upper mechanical arm. The upper fixing base plate 11 is fixedly connected to the upper mechanical arm by fasteners.

[0041] As shown in Figure 2As shown, the upper moving crossbeam 12 is preferably a semi-cylindrical structure, and a gap is provided between the semi-cylindrical structure and the fixing base for the tendon and the inner support to pass through. When in use, one end of the tendon passes through the hole in the upper fixing device fixing base from above or below the upper moving crossbeam, and then the two ends of the tendon are parallel to each other in a walking shape downward, that is, the two free ends of the tendon naturally sag under the action of gravity.

[0042] As shown in the drawings, Figure 3 The clamp mechanism 2 is provided with a trapezoidal groove 25, and is also provided with a guide hole and a fixing hole.

[0043] As shown in the drawings, Figure 4 and Figure 5 The trapezoidal groove 25 is provided with two clamping blocks 26 for clamping. The bottom of the clamping block 26 is provided with a threaded hole 28.

[0044] The trapezoidal groove 25 of the clamp mechanism 2 is also provided with a guide sliding groove 24, and the two sides of the clamping block 26 are provided with guide protrusions 27, which are matched with the guide sliding groove 24.

[0045] As shown in the drawings, Figure 7 and Figure 8 The upper end of the clamp base 3 is provided with a guide column 34 matched with the guide hole, and the outer side of the guide column is provided with a spring assembly. The spring assembly is preferably a spring because of its simple structure and convenient installation. When it is necessary to open the clamp, the clamp mechanism is pressed downward, the clamp mechanism 2 runs downward, the spring is compressed, and the two clamping blocks 26 are clamped. When the external force is removed, the spring returns to the normal state, and the two clamping blocks are opened.

[0046] The clamp base 3 is also symmetrically provided with two positioning grooves 32, which are matched with the position of the trapezoidal groove 24 on the clamp mechanism 2. In use, the bolt used as a fastener passes through the positioning groove, so that the clamping block 26 and the clamp base 3 are connected as a whole. The guide column 34 is also sleeved with a spring 35.

[0047] In this embodiment, the positioning groove is preferably a U-shaped positioning groove, and the fastener can slide in the positioning groove.

[0048] The clamp base 3 is also provided with an inner support fixing hole 36 for the inner support to pass through, as well as a threaded hole 38 and a connecting hole 33 for connecting and fixing with adjacent components. The inner support fixing hole 36 is provided with an inner support crossbeam 37.

[0049] The lower part of the clamp base 3 is also provided with a lower fixing base, and the lower fixing base is provided with a groove, and the groove is provided with a sliding rail 40, and the sliding rail 40 is provided with a lower moving crossbeam 39. The lower moving crossbeam 39 can move up and down along the groove where the sliding rail 40 is located, and the up and down movement of the lower moving crossbeam 39 can change the looseness of the inner support wound on the inner support crossbeam. The lower moving crossbeam is preferably a semi-cylindrical structure.

[0050] The specific applications of this utility model are as follows:

[0051] The internal support is relaxed relative to the tendon. In this invention, one end of the tendon passes through a hole in the fixing seat of the upper fixing device below the upper moving crossbeam. The tendon is positioned between the upper moving crossbeam and the fixing seat, with its two free ends hanging naturally. These two free ends are clamped downwards and fixed within two clamping blocks. Similarly, the internal support passes through a hole in the fixing seat of the upper fixing device below the upper moving crossbeam. The two free ends of the internal support hang naturally, passing through the gap between the two clamping blocks and the fixing hole of the internal support. One end is wrapped around the fixing crossbeam of the internal support, ensuring that the semi-cylindrical structure of the lower moving crossbeam is tightly attached to the fixing crossbeam of the internal support and the surface of the wrapped internal support. The two free ends are then passed through the lower part of the semi-cylindrical section of the lower movable crossbeam and tied in a knot. After securely tying the knot, the lower movable crossbeam is removed, thus achieving a 2mm relaxation of the internal support relative to the tendon.

[0052] The tendon is relaxed relative to the internal support. The internal support passes through a hole in the upper fixation device's fixing seat below the upper movable crossbeam. The two free ends of the internal support hang naturally, passing through the gap between the two clamping blocks and the fixing hole of the internal support. One end is wrapped around the internal support fixing crossbeam, and the two free ends are tied together for fixation. The upper movable crossbeam is placed close to the surfaces of the upper fixation device's fixing crossbeam and the internal support. The tendon passes through a hole in the upper fixation device's fixing seat above the upper movable crossbeam and folds back. The two free ends fold downwards and are clamped in the two clamping blocks for fixation. After fixation, the upper movable crossbeam is removed, achieving a 2mm relaxation of the tendon relative to the internal support.

[0053] In one embodiment, the internal support can also be fixed to the internal support beam in other ways.

[0054] like Figure 9 and Figure 10 As shown, the lower fixing mechanism 4 is located at the lower end of the clamp base 3 and is used to connect the clamp base 3 and the lower robotic arm into one unit.

[0055] The lower fixing mechanism 4 includes a hollow receiving base 41 and a lower fixing base 43. A support column 42 is provided between the receiving base 41 and the lower fixing base 43. Both the receiving base 41 and the lower fixing base 43 are provided with connection holes for connecting with adjacent components.

[0056] The above-mentioned structural design of this utility model can not only fix the tendon and the internal support respectively by adjusting the upper or lower moving crossbeam, but also quantitatively simulate the relative relaxation of the internal support and tendon fixation during surgery.

[0057] The design of the lower fixing mechanism in this utility model is ingenious, providing sufficient operating space for the operation below the fixing device and improving the ease of use of the device.

[0058] While the embodiments of the present application have been illustrated and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the spirit and scope of the application, which is defined by the appended claims and their equivalents.
